According to a petition at change.org
At first glance, Greg Schiller looks like a mad scientist taken straight out of a Hollywood film. His infamous moustache has more fans and followers than the dodgers on a good day. He coaches fencing and occasionally appears in school talent shows. Heck! Mr. Schiller is in fact anything but ordinary. He is teacher, role model and friend.
He is also suspended from teaching, coaching, and acting as union rep for his school.
Schiller was ordered to report daily to a district administrative office pending an investigation after two students turned in science-fair projects that were designed to shoot small projectiles.
One project used compressed air to propel a small object but it was not connected to a source of air pressure, so it could not have been fired. (In 2012, President Obama tried out a more powerful air-pressure device at a White House Science Fair that could launch a marshmallow 175 feet.)
Another project used the power from an AA battery to charge a tube surrounded by a coil. When the ninth-grader proposed it, Schiller told him to be more scientific, to construct and test different coils and to draw graphs and conduct additional analysis, said his parents, who also are Los Angeles teachers.
A school employee saw the air-pressure project and raised concerns about what looked to her like a weapon, according to the teachers union and supporters.
Shooting objects through tubes has a long tradition, and the idea of moving things with coils has been around a long time (I dimly recall articles about coast-to-coast coil trains from old mouldy Popular Science mags).
If you support freedom of scientific thought in our schools you might want to stop by change.org and sign the petition.

I can't speak about schools here in the UK, but some of my old university friends used to be very keen on building potato cannons. These were physics and engineering students, so they weren't going to build a little low powered toy. It was a very substantial steel tube with electronic ignition/trigger systems. I once saw it fire an orange hard enough to dislodge bricks in a wall.
They told me about some of the earlier tests, when they were looking for a good outdoor place to fire it, and (rather foolishly) chose a spot a few miles down the flightpath from a large city airport. It was not a quiet device so they were heard, and the police turned up very quickly to find out what was happening.
They got a verbal warning about finding a more appropriate firing range, and after the officer had checked their cannon to be sure they wouldn't blow themselves up, an off the record congratulation for building the cannon so well.

+1, sudden outbreak of common sense.
